5 Tips to Keep Cooling Costs Down

Tuesday, May 19th, 2015

With summer on the way and temperatures already starting to rise, we are all looking for ways to keep our cooling costs as low as possible. It’s a fact of life living in the desert: having an efficiently running a/c unit is a necessity.

 

The US Department of Energy cites that heating and air conditioning your home accounts for almost 50% of the energy use in a typical US home, making it the largest energy expense for most homeowners. In fact, it costs US homeowners $11 billion every year just to run their air conditioners.

Energy efficiency is one of the easiest and most cost effective ways to reduce high energy bills. Here are 5 tips to keep cooling costs down:

  1. Replace your old, inefficient HVAC unit. John’s offers no- to low-interest financing on new a/c units.
  2. Regularly clean or replace your air filters (ideally, once a month) to improve the efficiency and life of your unit. John’s offers a filter service where we bring out a year’s worth of filters so you don’t have to remember to buy them.
  3. Air conditioners make us feel cooler by reducing the amount of moisture in the air. Living in the Arizona desert, though, means we often need to add humidity. John’s can help you determine the right amount so you feel comfortable in your home.
  4. Simply running fans in the rooms where people gather is an inexpensive way to keep cooling costs low. Ceiling fans should be turning in a counterclockwise rotation during the summer. And fans don’t work on empty rooms, so turn fans off (just as you should be doing with lights) when a room is unoccupied.
  5. Shading your home from the brutal sun’s rays is very important to keeping your house cooler. Plant trees on the east, south, and west sides of your house, if possible. Replacing bug screens with shade screens on all your windows help a lot, too.

John’s has NATE–certified technicians that offer you solutions to the many problems homeowners face when dealing with cooling your home. Just Call John’s to find out how we can help you.

Do you qualify for money-saving SRP rebates?

Wednesday, February 18th, 2015

When you Just Call John’s, you know you’re calling a team that has your best interests in mind. Not only do we want your home a comfortable temperature, we want it to be as energy efficient as possible. That’s why we’ve partnered with SRP as certified technicians in their energy upgrade SRP rebates program.

What is an energy audit?

Our technicians are certified to perform energy audits and make recommendations for energy upgrades that are covered under the SRP rebates on energy upgrades. We will talk to you about your energy efficiency concerns, including:

  • Cold/warm air coming into the home through doors and windows that aren’t properly sealed
  • Insulation that is missing or not properly installed
  • Temperature variance of 2-5 degrees in different rooms of the home

We will then inspect and test your home, including ductwork, attic, crawl space, air conditioning and heating unit, insulation, appliances, and lighting to determine inefficiencies and identify areas where you could be saving money on electricity.

Energy inefficiencies include:

  • Use of lightbulbs that are not energy efficient
  • Non-Energy Star appliances
  • Older HVAC units (these are less energy efficient; see new SEER requirements)
  • Improperly sealed ductwork, windows, and doors
  • Negative pressure and/or lack of fresh air

After the energy audit, our technicians make recommendations for changes to your home. Some of these upgrades may be covered by SRP Energy Upgrade Offers:

  • Air Sealing Rebate – When air isn’t travelling efficiently through the system, the air in your home can contain dust, pollen, and other contaminants that are unwanted, especially if you have allergies or asthma.
  • Insulation Rebate – Not only should your home be well insulated, the installation should be properly installed and free of gaps, voids, and compressions.
  • Duct-Sealing Rebate – As much as 20% of the air in the duct system could be lost through leaks if ducts aren’t sized and sealed properly. That means the system is working harder to keep your home a comfortable temperature. The result? Your utility bill is higher than it would be if the ducts were properly sized and sealed.
  • High Efficiency System Rebate – If you’re tired of maintenance on your unit or your unit is tired of working, it could be time to invest in a high efficiency unit. The investment is worth the cost, especially if you get a rebate AND save money on utility bills.
  • Shade Screen Discount – One of the most affordable ways to keep summer sun from heating your home is to have shade screens installed.

If you’re ready to learn how you can save money while making your home more energy efficient, Just Call John’s for an energy audit today!

Should we try what China is doing by fighting pollution?

Wednesday, November 26th, 2014

It has recently been reported that China has designs for towers that will filter air and water in highly populated and polluted cities. At the base of the towers are greenhouses that could, at least in theory, grow vegetation, including fruits and vegetables, throughout the year. It sounds good in theory, but should we try what China is trying by fighting pollution?

Maybe. Maybe not.

At this point, it’s just theory and a set of drawings. We, including China, don’t know if the tower will be worth the resources spent to create it. Resources that include the environment.

In order to make space for new towns and suburbs, engineers are suggesting that the tops of mountains would need to be sliced off in order to fill the valleys caused by the construction of the immense towers. That in and of itself has environmental implications beyond fighting pollution, including what would happen to the wildlife and ecosystem of these mountainous areas.

But…

China’s air pollution is reportedly so bad that it is often compared to a nuclear winter. Crops are damaged and there is a real threat to their food supply. They, rather than the U.S., might be more likely to build the air and water filter towers.

Should we try what China is trying by fighting pollution?

Let’s look at the viability of creating a monstrous tower. In densely populated cities like New York, Chicago, or Los Angeles, we would have to destroy private and public land to even have space for this type of tower. That alone would have environmental and political implications.

While there are places in the U.S. with poor air quality, no area comes close to a nuclear winter. So is it worth it – even if we can scrub our air and water clean – to build such a tower?

Maybe. Maybe not.

We’re not a government-controlled nation (like China) that can make blanket decisions for the people. The reality is that between politicians, businesses, and environmentalists, an air and water filtering tower is probably never going to happen.

 

And China hasn’t even built one yet so we don’t have a real case study to review.

Until someone else builds it, we don’t think it’s happening here. No matter how good it sounds in theory.

What is a radiant barrier and is it worth the cost to install in your home?

Wednesday, November 12th, 2014

The Department of Energy describes a radiant barrier as a highly reflective material that reflects radiant heat rather than absorbing it. It is installed in homes, usually attics, to reduce summer heat gain and reduce cooling costs.

 

Sounds great, especially for the Arizona summer, at least in theory. Before you’re sold on the idea, let’s look at whether or not a radiant barrier is worth the cost.

  1. The easiest homes to install radiant barriers are new builds. In an existing home, it is best to install in an open attic.
  2. As with A/C units, the efficiency is dependent on the installation. While you can install yourself, we recommend hiring a RIMA International certified installer who understands which type of barrier is best for your home and the proper place for installation.
  3. Choose the type of barrier that is most appropriate for your climate and home. Radiant barriers are available in reflective foil, reflective laminated roof sheathing, and metal roof shingles. In Arizona, it is recommended that you use reflective foil.
  4. Location of the barrier is as important as the type of barrier you select. Simply laying a foil barrier on the attic floor will not be effective as it will gather dust, dirt, and other contaminants quickly.
  5. Other factors to consider are the cost of hiring a contractor for installation, the size of your house, and how accessible the attic is.

As with any home improvement project, it is important to ask a lot of questions of professionals as well as from your neighbors and friends. You also want to research the options yourself so you’re an informed consumer.

Energy Efficiency – Will this DOE change matter?

Wednesday, November 5th, 2014

In an effort to continue making American homes more energy efficient, the U.S. Department of Energy (DOE) is increasing the minimum federal standard for air conditioners in the southern United States, including Arizona, from SEER 13 to SEER 14 effective 1/1/2015.

 

At John’s Refrigeration, we are dedicated to keeping our customers safe and comfortable and will, of course, comply with these changes. We also believe that the energy efficiency of your home depends on much more than the SEER rating of your AC unit.

Let’s start by defining Seasonal Energy Efficiency Ration (SEER)

Seasonal Energy Efficiency Ratio (SEER) is the total cooling output (in British Thermal Units or BTUs) provided by the unit during its normal usage period divided by its total energy input (in watt hours) during the same period. The higher the SEER rating, the more efficient the unit. In theory, the SEER 14 is a more efficient unit than the SEER 13.

The SEER Challenge

The rating is derived in a laboratory setting with a steady temperature of 85 degrees, well below temperatures we see here in Arizona. In addition to the temperature, the testing room has perfectly installed ductwork. In other words, it’s a closely controlled environment that represents almost no home in America or anywhere else.

The Solution

While we believe the SEER 14 units will provide greater energy efficiency, our team of certified and trained technicians will continue to inspect and repair duct systems, as they are the key to energy efficiency. As much as 20% of the air that moves through a duct system can be lost to leaks and improper installation. We strive for efficiency, not only in the units we install, but in the entire system of your home.

Ways to Stay Cool in Phoenix

Wednesday, July 24th, 2013

With temperatures still above 100°, the metro Phoenix area continues to experience extreme heat. We’ve all heard the mantra to drink more water, draw the curtains in your home to keep out the sun, and to limit the amount of time spent outdoors in order to not become overwhelmed by the desert heat. But there are other ways to stay cool in Phoenix, too.

 

  • Something as simple as eating smaller meals, or grazing, instead of eating three large meals a day can help keep you cool. The body has to work to digest what we eat, which heats us up. 
  • Placing a bed sheet in a baggie in the freezer an hour or so before bedtime and then sleeping under or on it can help cool your body temperature down, too.
  • Filling a hot water bottle with ice instead and keeping it near your feet while you sleep also helps.
  • Submerging your feet and/or arms into cool or cold water almost instantly cools our core body temperature. Even the occasional ice cube placed on the wrists offers quick relief.

Years ago, before air conditioning became as commonplace as it is now, people placed bowls of ice in front of fans and the air moving across the ice would cool down a small room or anyone who sat in front of it. Hanging a wet sheet in front of a fan – taking care the sheet doesn’t get pulled into the fan’s blades – also works to cool down an area. These tips would be great to use outdoors on a porch during the hot summer months.

The Center for Disease Control and Prevention states “Air-conditioning is the number one protective factor against heat-related illness and death.” Making sure your a/c is running correctly is what John’s Refrigeration Heating and Cooling does. As your home comfort partner, John’s has Certified Service Consultants ready to help keep you and your family cool and safe. But we’ll still remind you to drink water, too.

Six DIY Energy Saving Tips for Homeowners

Monday, July 22nd, 2013

Making your home energy efficient is complicated business. From sealing and insulation to how we live in our home, there are many ways to lose energy efficiency. At Johns Refrigeration we offer a 51-point inspection of the HVAC system including the ductwork of the home. Our Peak Performance Home Evaluation includes air and pressure balancing or pressure checks, an option for incorporating a fresh air component to the system and more. As a homeowner, there also things you can do to make your home more efficient.

Did you know? As much as 80% of energy savings comes from 20% of needed repairs which is why we offer the following six DIY energy saving tips for homeowners:

  1. Sealing around wall or ceiling registers: By sealing the registers you are helping to eliminate dust, dirt, pollen, other contaminants and hot air from entering your home via the attic and air-conditioning system.
  2. Insulating and sealing the attic hatch is a forgotten task for many homeowners. It’s a place where air can be lost or drafts can occur decreasing the efficiency of the HVAC system and increasing energy costs to you.
  3. Install shade screens on the outside of the home. This actually has a greater return on investment (ROI) than replacing windows and doors, at least here in the Arizona desert. The shades prevent the sun from heating the home as much as its non-shaded counterparts. It will take less energy too cool it saving homeowners energy costs.
  4. Stop closing doors. Many homeowners are under the false assumption that closing doors helps save energy when the opposite is actually true. Ideally the entire home should be at a neutral pressure. Closing doors causes a positive or negative environment which causes cool air to escape or brings hot air and contaminants in from outside the home. Keeping the doors open helps keep pressure closer to neutral and your system working more efficiently saving you money.
  5. Programmable thermostats are a great way to regulate energy use and utility cost. Some even have the option of controlling the HVAC system right from your cell phone! Check out our article about selecting and installing the right thermostat for your home.
  6. Choosing the right air filter can not only make your home energy efficient, it will also lower your energy costs. Select a filter that is low resistance and high efficiency. If the filter you use is “sucked” into the space, you are using a filter that has too high a resistance. You’re actually making the system work harder; it’s like it is breathing through a small tube or having an asthma attack – the system has to work harder to cool your home. Less resistance is like breathing without asthma – it is smooth and efficient. We recommend the Aire Care filters which are low resistance and 84% efficient. Call us to learn more about these filters.
